Product Properties
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.
major application
P 61TV-956L is widely used in hand lay-up and spraying processes. P 61TV-956L has low viscosity and very good infiltration of fiberglass.P 61TV-956L has been approved by China Classification Society and has good water resistance and small shrinkage, mainly used in shipbuilding industry and nacelle manufacturing.

Instructions for use and precautions
- 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.
