CLEAR RIGID EPOXY RESIN
This CLEAR RIGID EPOXY RESIN system is specially formulated for decorative applications including casting.
It is totally clear and UV stabilized giving excellent optical properties with negligible to no shrinkage on curing.
PLEASE READ ALL THESE NOTES BEFORE USING.
It can be used for casting decorative parts featuring a long working time, ease of use and low exotherm. Ensure ambient material and workshop temperature is between 18 to 25ēC and humidity level below 70%.
Mixing by Volume
Mixing is critical and must be accurate. 2 parts resin for 1 part of hardener will provide a hard casting once cured. Pour the hardener first then the resin. The combined liquids must be thoroughly mixed manually or mechanically to completely remove any haziness or streaks, scraping the sides and base of the mixing pot then transferring the mix to a second container and stirring is best practice for good castings. An entirely homogeneous mix is essential in achieving optimal results. It is important to only mix the correct quantity at a time as epoxy systems tend to exotherm when kept in a mass.
(Mixing by weight: 100g resin to 45g hardener pro rata).
It can then be poured into a mould. The mould can be a hard mould or made of silicone rubber. Moulding can be carried out by gravity or under vacuum. It does not trap air easily and does not heat up when used properly. Temperature should be between 18 to 25ēC. Humidity level below 70%. Pot life is as follows for a 500g mix at 22ēC 2+1 mix=10 hours. The hard mix (2+1) will provide a hard casting, suitable for manufacture of fancy shapes, decorative items etc. Should a new mix be applied onto cured resin, the contact surface should always be sanded in order to enhance adhesion.
Parts can be released after the following time at 22ēC. 2+1 mix =19 hours.
Physical & mechanical properties
Properties given for a temperature of 22ēC.
Resin: Clear liquid, viscosity of 1,000 mPas.
Hardener: Clear liquid, viscosity of 150 mPas.
Mixture: Clear liquid, viscosity of 300 to 450 mPas.
Mixing density: 1.1.
Hardness: 95 Shore D (2+1 mix).
Elongation at break: 8% for the 2+1 mix.
Tensile strength: 66 MPa (2+1mix).
Flexural strength: 105 MPa (2+1 mix).
The optimal mechanical properties will be reached after 21 days at 20ēC or 15H at 60ēC.
Resin is crystalline and/or opaque Storage at below 10ēC
Sit resin container in medium hot water or on a radiator and agitate contents frequently until it becomes clear again. It can now be used as per instructions.
Only when liquid does resin react to low temperatures in this way, when properly catalysed and fully cured the resin retains its clarity permanently.
PACKING & STORAGE
Shelf life is one year in sealed containers as provided. Keep containers sealed and away from heat and cold.
HEALTH & SAFETY
This product is a modern formulation of the safest epoxy chemicals available. It is however advised to follow basic rules such as avoiding skin contact, wear masks when producing dust.
