Analysis of color variation of sponge spray glue.
BIGGER received advice from customers about why some of the sponge glue used for a period of time would be darker or darker.In view of this phenomenon, BIGGER is to answer for everybody, why the color of sponge glue will become deep?
The reasons for the color variation of sponge glue are as follows:
1.        Some customers are not well managed.Some products have been overstocked for a long time, and the storage temperature is high, causing the color of sponge spray to deepen.
2.        During the transportation of the packaged products, the backlog and collision occurred between the goods, which caused the leakage of some packing barrels or the bad seal, which led to the air, impurities and so on into the packing bucket to make the color of the sponge glue gradually darkened.
3.        Sponge glue color changes are the main component of rosin resin viscosity, the composition of acid value is higher, easy to stick, air and other produces chemical reaction, which changed the original color, with the increase of time, gradually become dark, until dark.
terms of settlement:
1.        In the process of use, especially the uncompleted sponge spray glue, do the sealing work to avoid the long exposure of the sponge spray adhesive to the air.
2.        Part of damaged sponge glue with drum in transportation is preferred.Stock of sponge glue, to sell first to buy first.
3.        In addition, in general, the product of sponge spray glue, although the color changes, but does not affect its bond performance, the customer can use normally.
