Palatal P61TV-956 is a pre-accelerated, thixotropic unsaturated polyester resin from AOC’s Palatal resin range, supplied by Thousands Technology for composite fabricators sourcing a general-purpose orthophthalic resin for hand lay-up and spray-up work. This resin is formulated on orthophthalic acid and standard glycols dissolved in styrene, designed for easy processing with rapid impregnation and defoaming speed that helps fabricators keep wet-out times short during lay-up.
Palatal P61TV-956 Key Properties
Per the manufacturer product data sheet, Palatal P61TV-956 has a flash point of 33°C (TM 2800) and a stability (no initiator, dark, 25°C) of 3 months. As an unfilled casting, cured with 2.0 g Butanox M50 per 100 g resin and post-cured 24 hours at 80°C, this resin reaches a tensile strength of 55 MPa and tensile modulus of 3.2 GPa (ISO 527-2), a flexural strength of 90 MPa and flexural modulus of 3.0 GPa (ISO 178), a heat deflection temperature of 65°C (ISO 75-2), and an unnotched impact strength of 8 kJ/m² (ISO 179). These figures place it among standard orthophthalic laminating resins used across general FRP fabrication.
As a pre-accelerated, thixotropic grade, this resin requires only the addition of a peroxide catalyst such as MEKP before application, with a built-in color change system that helps operators track cure progress during hand lay-up. Its low viscosity and high reactivity support consistent wet-out of fiberglass reinforcement without running off vertical surfaces, which is particularly useful for boat hulls, tanks, and other large vertical or overhead laminate sections.
Key Features
- Good mechanical property for structural laminate strength
- Rapid impregnation and defoaming speed during hand lay-up and spray-up
- Low viscosity with high reactivity and manageable gel time
- Built-in color change system for visual cure monitoring
- CCS and LR marine classification society certification
Because the resin’s thixotropic index is tuned for vertical and overhead work, it holds reinforcement in place during build-up of multiple laminate plies without excessive drainage, which helps fabricators control laminate thickness and resin-to-glass ratio across a part. Consistent batch-to-batch viscosity and gel time also make scheduling easier for shops running multiple hand lay-up or spray-up stations in parallel, since operators do not need to re-adjust catalyst dosing or working time between deliveries.
Main Applications of Palatal P61TV-956
Palatal P61TV-956 is well suited for hand lay-up and spray processes, where it rapidly impregnates reinforcing materials and resists running off on vertical sides. Fabricators use it across marine, sanitary ware, leisure, and cabin industry laminating, where consistent mechanical property and surface quality are required. For buyers building out a full laminate system, Thousands Technology’s resin range pairs with a suitable organic peroxide catalyst such as MEKP to match the required gel time and cure profile for each application.
Because hand lay-up and spray-up production schedules depend on consistent viscosity, reactivity, and gel time from batch to batch, industrial buyers sourcing Palatal P61TV-956 typically request a current technical data sheet before scaling up purchase volumes and maintain a qualified secondary supply channel to protect production from single-source disruptions.
Safety and Handling Considerations
This resin should be stored in a dark, dry place at temperatures between 5°C and 30°C; shelf life is reduced when it is stored at higher temperatures, and it should be kept in dark, 100% light-tight containers away from direct sunlight. As with other unsaturated polyester resins, handlers should use appropriate personal protective equipment when working with the uncured resin and its peroxide catalyst. A Material Safety Data Sheet is available on request, and Thousands Technology can supply the current TDS and SDS alongside each order.
