 Waterproofing Agents
 |
For applications which require waterproofness, N type GOHSENOL is recommended.
N type GOHSENOL is inherently waterproof. Its waterproofness can be notably enhanced with heat treatment. The higher the heat treating temperature, the better the obtained waterproofness.
In the cases of A or G type GOHSENOL, a waterproofing effect can be obtained by using a waterproofing agent.
As with N-type, the higher the heat treating temperature, the better the waterproofing effect. As waterproofing agents, glyoxal, dimethylol urea, and trimethylol melamine are recommended.
The following chart shows the waterproofing effect evaluated by a swelling ratio and an insoluble residue:
