Technological parameters

Mixing ratio (by weight)	RT521-A : RT-521B = 100:45
Mixing ratio (by volume)	RT521-A : RT-521B = 2:1
Mixing viscosity (25ºC)	500-800 mPa·s
Applicable period (25ºC,100g)	5-6 h
Initial curing(25ºC)	Approx. 24-30 hours at room temperature
Final curing (25ºC)	Approx. 3-4 days at room temperature
Operating temperature range	10ºC-40ºC
Points for attention	The amount of glue should be adjusted according to the operable time and the amount of glue used. Please keep the glue container clean and weigh it accurately according to the weight ratio of component A and B. Stir it fully clockwise along the inner wall of the container and remove the air bubbles after vacuuming. The lid of the barrel must be sealed after the use of B glue to avoid the product being scrapped due to moisture absorption.

Typical properties and shouldn't be regarded as a product specification.

 

Storage and shelf life

1. RT-521A epoxy resin has a chemical use deadlines of 12 months under storage conditions of 25ºC to 35ºC, dry and in the original sealed package.
2. RT-521B curing agent should be put in the original package, placed in a dry and cool place, avoid direct sunlight, the temperature is not higher than 30ºC, its chemical properties can be maintained for 6 months unchanged, high temperature and direct sunlight will accelerate the yellowing of the product.
