BD40261 chemical corrosion resistant epoxy resin coatings

Product usage of BD40261 chemical corrosion resistant coatings:
This product is the chemical corrosion resistant polymer material which compounded by modified toughening resin and variety corrosion resistant materials,it is widely used in the preparation of corrosion resistant coating on the surface of machine part which has corrosion resistant requirements.Especially used for the pre-protection of pumps,valve,pipeline,heat exchanger end plate,blade and tank body etc.equipment new parts and repairing and renewing the above equipment.

Performance features of chemical resistant epoxy resin coating:
1.Effectively resist all kinds of solution corrosion and not easy to discolor.
2.After curing,the surface is smooth and delicate, easy to clean and maintain.
3.strong adhesion, high mechanical strength, no obvious shrinkage after curing.

How to use:
1. Surface treatment: the original floor surface shall be cleaned,use a grinder for full grinding,and the damaged,sand-generating,cracking and hollow parts shall be completely exposed and polished to the compacted base. The defective parts shall be repaired and leveled.After treatment, the floor surface should be flat, dense, dry, no oil and no loose brittle particles.

2. Preparation: mix proper amount of A and B components in the required proportion and stir them evenly.The prepared repair materials should be used up within the prescribed operation time limit (that is, used up before the repair materials start to become sticky), and the materials after becoming sticky and hard can’t be reused;

3. Coating: brush, roll or scrape the evenly mixed materials onto the floor surface with a trowel. Pay attention to the thickness control.

4. Curing: after curing 24 hours at 25℃, the electric spark detector will detect and confirm that the coating has no leakage point and can be put into light load use;If found that when the temperature of construction environment is too low, curing can be done by heating or extending curing time.

Special version:
1.This parameter is for laboratory conditions,due to the actual working condition is more complex,suggest the users to do the pretest according to actual working condition
2.When the environment temperature is below 15℃,the curing time will prolong,should take proper heating measure
3.When the environment temperature is more than 25℃ or the mixing quantity is too large,the curing speed will expedite,should properly shorten the application time of coating after mixing.

Transportation storage
Sealed storage in the cool and dry place. The warranty period is 12 months. Avoid placing it upside down, knocking against and transporting it as a non-dangerous product during transportation.

Packaging specifications:
Two components,20Kgs/set,packed in a plastic drum.
