P 61TV-956L is a pre-promoted, thixotropic o-phenylene unsaturated polyester resin with low viscosity and high reactivity, suitable for hand lay-up and spraying processes. The resin contains a low styrene evaporator (LSE) and a color change indicator for the curing process. It has good wettability to glass fibers and excellent handling properties.
P 61TV-956L has excellent mechanical properties and good water resistance.

Curing agent can be used MEKP, the dosage is 1.0~2.5%. it should be ensured that the curing agent is within the validity period.
Palatal P 61TV-956L resin already contains accelerator. The thixotropic agent in the resin may gradually precipitate after long-term storage. It is necessary to disperse it evenly before use, either by rolling the drum upside down several times or by stirring it properly in the container.
For better performance, the product can be post-cured at 80°C for several hours.
