HAPWELD 36

Excellent bond strength      100% solids     2:1 to 1:1 by weight or by volume         Reliable

• A two part, non-shrinking, 100% solids, amber clear, polymer adhesive which cures at room temperature. It is a flowable polymer adhesive which forms permanent structural bonds between similar and dissimilar materials. 

• Once hardened, HAPWELD 36 resists moisture, water, solvents, chemicals, and retains good bond strength up to 160°F.

• May be used from 2:1 to 1:1 by volume or by weight, making it ideal for both field and production applications. 

• 
  The "workhorse" of our polymer adhesive line and will bond most metals, plastics, ceramics, wood, fabrics, canvas, etc. As you increase the mix from 2:1 to 1:1, the cured product becomes semi-rigid and has lower heat resistance.

HAPWELD 37

 Adhesive / filling & filleting putty       Machinable      Color coded for even mix       Will not sag
  

• HAPWELD 37 A/B is a thixotropic (putty-type) version of HAPWELD 36 A/B.

• HAPWELD 37 has a creamy, non-sag consistency, which can be applied with a trowel, knife, or brush, and adhesive will not sag or shrink. The smooth consistency allows the user not only to use HAPWELD 37 as an adhesive, but also as a void filling and filleting putty.   

• HAPWELD 37 can be easily machined; feather edged, drilled, tapped, turned in a lathe, sanded, and polished. It is compatible and will bond to most metals, wood, plastics, ceramics, fabrics, and compositions of almost any type.

• Another added advantage of HAPWELD 37 is that Part A is black and Part B is white. When mixed, they turn gray. This color-coding insures the user both a good homogenous mix and also allows the user to spot-check the mix ratio by color.

• Some proven applications are: filleting spot welded metal parts, forming a radius on foundry patterns, patching of all types, anchoring bolts and machines, repairing valves, shafts, bonding magnets, and repairing pitted bearing surfaces.

HAPWELD 38

 Adhesive / filling & filleting putty      Machinable      Fast set       Production grade adhesive

• Similar in most characteristics to HAPWELD 36 A/B, mix ratio, clarity, etc., but also has the ability to gel and cure very quickly (gel time, 5-10 minutes).  
• May be used in all the same type applications as HAPWELD 36 and should be used when either a faster set or cold cure is required. 
• In some applications, the need for exotic holding fixtures, or large amounts of storage or "rack space", is eliminated. 
• May be used in high production applications.

HAPWELD 39

 High strength     Low viscosity     Excellent for textile industry applications     Easy to use
 

• Similar in most characteristics to HAPWELD 37; mix ratio, consistency, color, etc., but also has the ability to cure fast (15 minutes @ 77° F) and will cure in temperatures as low as 0° F. 

• May be used when either a faster set (less than 1/2 hour) or cold cure are required.  
  This unique polymer adhesive lends itself to outdoor applications year round; patching tanks, repairing valves and shafts, repairing cement or brick, caulking, sealing, and all types of adhesive applications. 

• The decreased cure time also makes HAPWELD 39 ideally suited for faster, in line, production cycles.

*Depending on mix ratio. Longest working life is at 2 parts A to 1 part B, and the shortest is at 1:1 mixing ratio.

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.

A note on curing:
HAPWELD 36 & 37 must be cured 24-48 hours @ 70º F.
HAPWELD 38 & 39 will cure at temperatures as low as 0º F

GEL TIMES FOR HAPWELD 38 & 39:

100ºF     F 3-5 minutes
