● Instruction
1.In the process of product production, after heating and curing, the temperature should be lowered steadily to room temperature to avoid sudden cooling and product deformation or cracking, especially in winter.The cutting and polishing of quartz during production should be carried out after full solidification
2.The filler should be avoided moisture absorption , high moisture content will affect the solidification of products, leading to performance degradation.
