WB110 HEAVY-DUTY ANTICORROSIVE CURING AGENT

WB110 has the wonderful solubility with epoxy resin, extremely high reaction activity.it can fast harden, and its films has wonderful chemical resistance, solvent resistance, cathode removal resistance. and strong adhesive strength, flexibility, impact resistance, ete.

 

【Brief introductien】

 

WB110 heavy-duty Anticorrosive Curing Agent is a kind of modified hydroxyl resin with thermosetting linetype phenolic(also known as a kind of macromolecular polymer capped with hydroxyl group and catalyst ). WB110 can substitute D.E.H84 of DOW, America; It can combine with general bisphenol A type or modified phenolic epoxy resin, to manufacture highly active heavy-duty Anticorrosive powder coating. The film of this powder coating product has extremely strong resistance to chemical corrosion and mechanical property.

The reaction of WB110 and epoxy resin belongs to addition reaction, it has no escape of volatile substances during the film forming period, and no pinhole and stomata. So especially suitable for the work pieces needed thick-coated, such as petrol, natural gas pipes, pollution water pipes, steel rod used in building engineering, valves, elbows. fire equipments. and other irregular parts, etc.

 

【Technical data】

2. Soften point:85-95℃

3. Hydroxyl value:4.5-5.5 mol/l000g

4. Generally,100 portions epoxy resin 6825/6828 cured needs 20--25 portions WB110.

5. Need to add a small amount of additives to promote ring opening reaction of epoxy group, adjust the gel time, by the buyer to adjust according to the requirements

 

【Attention item】

 

1. The Composition proportion of epoxy resin and Curing Agent should be adjusted to the changes of epoxy resin.

2. Small-scale test should be repeated before production online.

 

【Packing. conveyance and storage】

 

Packing: Net 25 KGs, inside lining-polyethylene and double kraft paper bag packing.

 

【Transportation and Storage】

 

The epoxy resin and hardener can be stored and transported as the no dangerous goods, it was better stored in the original packing inside at 2-40 ℃, placed in the cool and well ventilated place, isolated the fire sources, kept off the hot resource. avoided the direct irradiation of sunlight. Commonly, the product storage period is one year. After the period, it still can be used if the examination is qualified.
