TDS 805 PT SG New

Polymal 805PT-SG is a thixotropic, pre-accelerated, unsaturated polyester resin that is pink in color. It exhibits good tack-free properties upon curing and is used to make glass fiber reinforced plastic products like boats, silos, and yachts that require multi-layer lamination over long fabrication times. The resin has a viscosity of 480-520 mPa.s, acid value of 18-22 mgKOH/g, and cures within 10-15 minutes with a peak exotherm of 110-130°C. When cured, it has a tensile strength of 60 MPa, flexural strength of 98 MPa, and heat distortion temperature of

RECOMMENDED STORAGE
Typical storage life at temperature below 250C is 3 months. To ensure maximum stability and maintain
optimum resin properties, avoid exposure to heat sources such as direct sunlight and steam pipes. The resin
should be stored in closed container below 250C and properly sealed to avoid moisture pick-up and
monomer loss. It is highly recommended to stir the resin prior to use.
