Description
Description:
Water resistant agent LS**1 is a modified melamine
formaldehyde resin, it features high content of resin, good
stability, good solubility, and easy for operation etc. The product
quality is better than the other products produced locally, and
reach the world advanced level. It can replace the imported water
resistant agent used in high concentration scraper coating
machine.
The resin LS**1 can give excellent wet strength , dry strength
and wet abrasion resistance, it can be widely used in the coating
of coated art paper, white board paper and card board paper, it has
good cross-link and compatible with the latex and starch in the
coating, it has no thickening, flocculation and blistering etc. bad
effect, and it can give good flow stability, and chemical stability
for the coating, it can also be used as surface sizing agent and
dry and wet strength agent for the high-quality paper, it can be
added directly in the coating material, and is easy to disperse the
material, and easy for operation.
The Water Resistant Agent LS**1 can also be used in the resin
dipping of decorative board and the crease-resistant and
