NO ACCELERATED POLYESTER RESIN

Product catalog summary

Product Overview: The document provides technical details about a non-accelerated polyester resin, which is an orthophthalic polyester resin known for its high reactivity and fast hardening properties. It is suitable for creating laminates with high mechanical performance.

Polymerization Characteristics: The resin polymerizes at 25°C using 1 g of cobalt octoate and 4 g of methyl ethyl ketone peroxide (PMEC) per 100 g of resin. Key polymerization times include a freezing time of 5 to 10 minutes and a peak time of 9 to 15 minutes, with an exothermic peak temperature ranging from 160 to 185°C. The resin can be made more thixotropic by adding up to 1% silica agent.

Physical Properties of Liquid Resin: The resin is yellow with a viscosity of 1.9-2.4 dPa.s at 25°C, contains about 40% styrene, and has a dry extract of 59-61%. It has a flash point of 33°C and a spontaneous combustion temperature of 490°C. The resin remains stable for 6 months when stored in darkness without catalysis.

Characteristics of Polymerized Resin: When catalyzed with 1.5 to 2% PMEC and 0.3 to 0.4% cobalt accelerator, the resin has a density of 1210 kg/m³ at 20°C, a voluminal shrinkage of 6.5%, and a BARCOL hardness of 47. It exhibits a tensile strength of 76 N/mm², flexural strength of 125 N/mm², and a modulus of elasticity in tension of 4200 N/mm². The resin's bending temperature under load is 74°C, with a MARTENS degree of 58°C and water absorption of 1.94% after 1000 hours at 60°C.

Application: The resin is suitable for molding, spraying, or impregnation. It should be mixed with 1.5% PMEC and applied to the fabric for rapid impregnation, especially with glass fabrics.

Packing and Storage: Available in 5 kg, 25 kg, and 220 kg packages. It should be stored in well-ventilated areas away from ignition sources, heat, and oxidizing products, ideally at temperatures between 15 and 25°C. Excessive heating can lead to self-polymerization with significant exothermic reactions.

Precautions for Use: The resin should be kept out of reach of children. Protective gear such as gloves, glasses, a breathing apparatus, and protective clothing should be worn during handling. Smoking is prohibited, and work should be conducted in well-ventilated areas.

Health and Safety: Refer to the data sheet for detailed health and safety information. The information provided is based on current knowledge and is intended to inform about the product and its applications without any guarantee.

DATA SHEET NO ACCELERATED POLYESTER RESIN This resin is a resin polyester orthophtalic, very reactive and with fast hardening, having good mechanical properties. It is a standard resin of general use, it allows the realization of laminates high mechanical performances. CHARACTERISTICS OF THE POLYMERIZED, NOT REINFORCED RESIN Catalyse: Resin + 1.5 to 2% of PMEC + 0.3 to 0.4% of accelerator to cobalt 3 APPLICATION The polyester resin can be used for moulding, spraying or impregnation. Add 1.5% of PMEC to the resin, mix carefully to achieve an even mixture. Apply the resin to the fabric to be impregnated. The resin impregnates glass fabrics very rapidly. PRECAUTIONS FOR USE Keep out of reach of children. To carry at the time of handling of the gloves, glasses, a breathing apparatus and protective clothing. Do not smoke when using. Work in a well ventilated area.
