Product Properties
P 65TV-958 is a thixotropic, pre-promoted general-purpose o-phenylene unsaturated polyester resin with low viscosity and high reactivity. In the resin
Contains wax solution.
major application
Byronic P 65TV-958 has low viscosity and very good infiltration of glass fibers, and is suitable for hand lay-up and spraying processes. The resin has good mechanical
Mechanical properties, shorter gel time. Good adhesion to both cast and extruded acrylic sheets. Low exothermic during curing, even if one-time
Laminated acrylic sanitary ware will not burn the acrylic sheet.
P 65TV-958 is particularly suitable for use with fillers, which can be used in quantities of up to 40-50phr, and is still suitable for injection processes.

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.
- After long-term storage, the thixotropic agent in the resin will gradually settle, and must be dispersed evenly before use.
- For better performance, the product can be post-cured at 80oC for several hours.
