HM-SA-WR49
HOWELL
WR-49 is a one-component sealant, which can be cured after contact with water vapor in the air. It is easy to operate and does not need to be stirred before use. It can be applied by manual or pneumatic glue gun. Before sizing, ensure that the surface of the base material is dry and free from pollution such as oil, grease and dust. After sizing, the glue surface must be repaired before the surface of the glue is crusted; when designing the glue joint, three-sided bonding of the sealant should be avoided.
