ABADUR HP-350 is two-component solvent-free epoxy coating derived from modified polyamines which is capable of acting as a protective layer on various surfaces. The unique formulation of ABADUR HP-350 allows to being continuously cured after immersing in water. This property also results in better performance on wet surfaces. The raw material used in formulating ABADUR HP-350 coating, particularly enhance excellent adhesion to the metal substrate while there is no need to surface preparation by primers. Plus, excellent chemical, abrasion and impact resistance is expected in this coating.
SURFACE PREPARATION
Concrete
All surfaces should be clean, dry and free from curing compounds, release agents, troweling compounds, standing water, grease, oil, dirt, bitumen coatings and loose or disintegrating concrete. All poured and precast concrete must also have blasted, wire brushed or acid etched to remove laitance.
Metal
All surfaces should be clean, dry and free from contamination. Prior to application all surfaces should be assessed and treated in accordance with ISO 8504. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Surface preparation shall not take place in the following conditions:
APPLICATION
Material is supplied in two containers as one unit. Always mix a complete unit in the proportion supplied. Once the unit has been mixed it must be used within the working pot life specified.
1-Agitate Part A and B separately with a power agitator.
2-Combine entire contents of curing agent (part B) with base (part A) and mix thoroughly with power agitator.
3-Mix thoroughly for at least three minutes, scraping the container bottom and side to assure complete mixing. There is no induction or waiting time required after mixing before application.
ABADUR HP-350 coating can be applied using good quality rollers or short haired brushes or by airless spray. It is recommended that ABADUR HP-350 coating be applied in two coats to ensure complete coverage. Prior to the application of each coat the surface should be examined for signs of pin-holing, etc. If the over-coating is delayed more than the drying time table, the previous coat must be thoroughly abraded to give an adequate mechanical key and solvent wiped. In hot climate, material temperature should be 20 to 25 ºC prior to mixing; otherwise pot life becomes very short. Do not thin for any reason.
