Epoxy resins tend to be the highest performance type of resin used in composites and are available with a wide range of different properties for specific uses including hand-laminating, resin infusion, coating, casting, flexible, repair and high temperature applications. Because of their high performance, epoxy resins are highly recommended for use with high performance reinforcements such as carbon fibre and aramid/Kevlar fibre.
All our epoxy resins have zero VOC content, are almost odourless and almost zero shrinkage. All epoxy products are sold as kits including both the resin and the correct amount of hardener; there is no need to buy the hardener separately.
Epoxy Resins generally have a higher density than polyester resins and are more transparent and adhesive than general-purpose polyester resins. Suitable for laminating and casting applications and often has enhanced moisture and chemical resistance.
Firstly, wear protective gloves to protect your hands against resin and hardener liquids exposure. Wipes can be used to remove resin that comes into contact with the skin, and any other resin that cannot be wiped off can be removed with a mixture of soap and water. We also recommend an exfoliant as an effective method for eliminating leftover bits from the skin.
A disposable apron or for industrial applications, overcalls, should be worn to avoid spilt resin making contact with skin or clothes. We also advise wearing safety goggles to protect your eyes. If resin makes contact with your eyes, you should repeatedly flush with water for 15 minutes and avoid rubbing. Medical attention should be sought as soon as possible.
You should be aware that there is some variation in the strength of epoxy resin varieties. The key strength values include shear strength, compressive strength, flexural strength, and peel strength. Epoxy adhesives offer the greatest level of tensile strength, with single component heat-curable adhesives typically having a strength of 35-41 N/mm2 (5100-6000 psi).
Curing is the best way to improve the mechanical, chemical, and heat resistance properties of Epoxy Resin. This involves the reaction of resin with suitable curatives for the formation of cross-linked thermoset structures. As with all resins, the ambient temperature is a key starting point, and ideally this will be 18-21 deg c.
There is some variation in the curing times required for different epoxy pastes and putties. We recommend that you cure the epoxy over the space of 72 hours. This is a warm, slow, and long process. This will allow the formation of strong adhesive bonds. The full curing time should always be allowed for on jobs that require the application of high pressure or stress.
The curing of epoxy resin may involve a reaction with itself, known as homopolymerisation. Or the formation of a copolymer featuring polyfunctional curatives or hardeners. You may increase the curing reaction's speed by adding small quantities of accelerators such as tertiary amines, carboxylic acids and alcohols.
Surfaces that are finished with epoxy resin but have taken on a dull or scratched appearance may be polished for optimum appearance. This will involve cleaning, sanding, and applying a polishing compound.
Answer:If you are going with the Resin Bonded Driveway System (spread resin and scatter aggregate) then you will only need the 1-3mm as it is small enough to stick. If you use any bigger, there is not enough of the stone surface stuck in the resin which will result in stones becoming loose over time.
Epoxy resins generally have a higher density than polyester resins and are more transparent and adhesive than general-purpose polyester resins. Suitable for laminating and casting applications and often has enhanced moisture and chemical resistance.
We also stock Epoxy Resin to include resins for craft or hobby projects. We stock three high grade, Clear Resins including two Casting Resins in a Fast Cure (up to 5mm castings) and Medium Cure (up to 80mm castings). These are ideal for resin river tables, bar tops, and counters. It can also be used for resin floors. Our second type of Clear Epoxy Resin is an Art Resin. This resin is designed to cover sculptures and artwork for added protection.
Epoxy Resin is extremely durable and easy to work with. Its superior qualities make it ideal for marine laminating applications where increased resistance to the elements is required. It is highly regarded within structural and engineering applications.
We ship our products throughout Europe, including Italy, Germany, Austria, France, Spain, Switzerland and the UK.In addition to innovative materials for work and creativity, the company offers its customers qualified support, providing instructions and techniques to easily work with resins in an accessible way.
Epoxy Resins are used in applications where superior strength, durability, and chemical resistance are needed. Epoxy Resin is more expensive than Polyester Resin and Vinylester Resins so the benefits should be considered before starting your project. Epoxies are available in different viscosities, low viscosity epoxies are used in RTM (Resin Transfer) applications. Epoxy resin cannot be thinned down to lower the viscosity with thinners as this will attack the chemical mechanisms that harden the epoxy, most manufacturers advise warming the resin carefully, bearing in mind also this will speed up the cure time.
With a growing assortment of products, our stock is updated regularly. We constantly strive to bring the very best and up-to-date materials to the community.

Epoxies come in resin form and are renowned for their high strength and versatility. As an alternative to polyurethanes and silicones, epoxy resins offer significantly enhanced adhesion and mechanical support while providing thermal transfer, chemical resistance, insulation and dimensional stability.

When formulating the epoxy resins and hardeners in the Entropy Resins product line, Entropy Resins go for the best physical properties possible with the lowest risk to both people and planet. This keeps the proportion of hazardous ingredients in Entropy Resins products low.
However, Entropy Resins products are still epoxy systems and classified as hazardous materials and should be handled with due care and attention to relevant Health and Safety measures. Further details can be found on -safety-tips/
Hardener selection comes down to the application in hand and the processing time required. This question is commonly asked in relation to the Clear Casting product CCR resin with CCF (Fast) or CCS (Slow) hardeners.
Always double-check the mix ratio on the hardener bottle and/or the Technical Data Sheet for the resin and hardener combination you are using before dispensing. It will be displayed as 100:**. Weigh out the resin quantity then take this resin weight, divide by 100 and times by the ** figure to determine the hardener weight req
