HS-2250 Unsaturated Polyester Resin for The Production of Large-scale Products

HS-2250 is an unsaturated polyester resin specially designed for polyester concrete. It has low viscosity, low shrinkage, good wettability with fillers to maintain a high filler rate, low volatilisation of styrene to improve the working environment, excellent workability, good air-drying property, which prevents sticking on the surface of the moulded products in a short time and forms a glossy and smooth surface. It is suitable for the production of large-scale products.

Note:

1) Pouring method is according to GB/T8237-2005. Curing system: accelerator HS-909 1.5%, AKZO M-50: 1.5%;

2) Curing system after casting body: Normal temperature (24 h) + 60°C (3 h) + 100°C (2 h).

Refer to the recipe for use:

                                            parts by weight

HS-2250 resin                                                                                                                              100parts

Accelerator HS-995                                       2parts

Curing agent (methyl ethyl ketone peroxide MEKPO)               1-2 parts (dosage depends on temperature)

Calcium carbonate / silica sand and other fillers                        600parts

Attention:

1. When the temperature of construction environment is high, the gel time is short, at this time, you can not arbitrarily reduce the amount of curing agent, but should reduce the amount of accelerator.

2. Because of the low shrinkage rate of the resin, in order to prevent the mould release difficulty, so it is recommended to use polyvinyl alcohol or fluorine type mould release agent.

Transportation should be in accordance with the State Council Regulations on the Safe Management of Chemical Dangerous Goods, Chapter V of the transport and handling of chemical dangerous goods. The product should be stored in a cool place under 25, avoid fire, isolate the heat source (such as direct sunlight or steam, etc.), and keep the barrel sealed to prevent moisture intrusion and volatilisation of the monomer.The shelf life is 3 months when stored under 25.
