Resin polyurethanne 78A and 78B - 1000 ml / flask
The white resin P.U. is a resin of casting which hardened very quickly. The product consists of a resin of color cremate on base of polyol and a hardener of MDI, 2 constituents mix very easily and very quickly ( some minutes), in complex moulds.

ADVANTAGES - total Absence of sediment in packagings - Absence of smell - not oily Surface after turning out - Adhesion between successive coats - Bass exothermie - Hardness of high surface - not porous in the manufacturing (polishing) - Weak retreat - Excellent thermal holding - is colored with colouring agents P.U.

CHARACTERISTIC Aspect: part A white liquid - Leaves B white liquid Density in 20°C: Part A 1.75 - Part B 1.22 Shelf life: 6 months in original packing closed under nitrogen.

CONDITIONS OF EMPLOYMENT: Proportions Leaves Has: 100 Weight parts Part B: 20 parts, Viscosity of the mixture in 25°C: 3400 mPa.s Hardness of life of the mixture: 1kg in 22°C 4-5 mn Temperature of implementation: 19-25°C possible Turning out after 45-75 mn

CHARACTERISTICS AFTER HARDENING - color white - density 1.65 - Hardness shore D after complete hardening 84 in 20°C - 80 in 70°C - linear retreat in 20°C 0.8 - 1.1 mm / m - compression resistance in 20°C 78 - 80 MPa - fold resistance in 20°C 66 - 68 MPa - traction resistance in 20°C 35 - 37 MPa

PRECAUTION OF EMPLOYMENT: The mindless employment of synthetic resins and their hardeners which can cause irritations of the skin or the general poisonings, the following precautions must be observed to eliminate these risks: ventilation of premises and jobs.
