Hapweld 1384 A/B
Directions For Use
SURFACE PREPARATION TO PREVENT ADHESION:
To prevent adhesion to the mold, use a GREASE IT release agent. The following are recommended; GREASE IT II, GREASE IT IV, GREASE IT V, GREASE IT FDG, GREASE IT WAX P, or GREASE IT WAX L. For best results, apply in a few thin coats, drying between coats. Porous surfaces, i.e. wood, plaster, etc, must be sealed thoroughly before release is applied. Use multiple coats of a good coating, such as: a high grade lacquer or urethane lacquer.
SURFACE PREPARATION FOR ADHESION:
For applications where adhesion is desired, the surface must be cleaned, abraded and dried. Sandblasting and mechanical roughing are the preferred ways of abrading surfaces to be bonded. For added adhesion to metals, use Primer 200, and for adhesion to plastic, use Primer 800. Make sure all surfaces are clean, dry, and free from moisture.
Use HAPCO’S ANTI-AIR to aid in air release (see Technical Bulletin). In some products, ANTI-AIR can cause a slight haze to cloudiness. This has no effect on properties.
Part A may freeze or crystallize in cold temperatures. Part A may appear to be striated, thicken, or solidify. This situation can easily be corrected. Place the cover on the Part A loosely (do not seal) and place in an oven set at 150-175º F for 3-4 hours. Reseal, allow to cool and then mix thoroughly.
Before each use, mix individual components, Part A and Part B, thoroughly before proportioning out the required amount. Components may separate and should be mixed before each use. Mix, only when ready to use, by adding the curing agent to the resin portion and blending together thoroughly. Be sure to scrape and stir in all material sticking to the sides and bottom of the mixing container. Do not use paper containers or wooden mixing sticks. They may contain moisture. For best results, use plastic or coated containers, and metal or plastic sticks. When mixing by hand, always be sure to scrape the sides and bottom of the container to insure complete mixing. When using the color-coded products (37 & 38), make sure a uniform color is obtained.
MACHINE MIXING AND DISPENSING:
Use HAPCO’S RAPIDFIL , MINIFIL and/or RAPIDSHOT Dispensing Equipment for fast, reliable, and efficient dispensing. CLEAN UP: Cured polymers are most difficult to remove. It is best to clean tools and equipment immediately after use. For best results, use Hapco's A-TAK. STORAGE: These polymer systems have a minimum shelf life of six months when unopened. Both components should be stored in a room temperature, dry place. When not in use, containers should be kept tightly closed.
Many polymers are moisture sensitive. Reseal using one of the following two (2) methods: blanket with nitrogen or use a hairdryer for 30 seconds to cover with dry air.
Skin or eye contact with polymers should be avoided. Clean housekeeping procedures are urged and the use of gloves and/or protective creams suggested. All polymers, as a general practice, should be used in well-ventilated areas. Spot ventilation is most effective. Contaminated clothing should be removed immediately and the skin washed with soap and water or waterless skin cleaner. Should accidental eye contact occur, wash thoroughly with water and consult a physician.
