Product processing guide

SunForce molded products can be joint to metal frames and other products.
Unlike conventional foamed products, SunForce’s superior strength allows fixing of screws possible.

Product Processing Guide

Fixing with nut, hollow spacer, washer and small screw.
Use spacer to maintain product structure and washer to enable stable fixing.

Tapping screw JIS Type-1
Fastening method
Directly tap without pilot hole
Length of screw
20mm

CAUTION) Please be sure to open pilot holes for M5 and above. For M4 or less, we recommend pilot hole to prevent cracking.

Adhesives

Fixing of SunForce using adhesive is also possible. Refer to table below for a list of adhesives recommended for use with SunForce.

Adhesion to metal plates (Aluminium plates and SUS plates)
Grades of adhesive Makers Composition Reference
Super-X2 Cemedine Co.,Ltd. Special polymer containing silyl group Operating temp. -76~248deg.F
SX720W Cemedine Co.,Ltd. Acrylic polymer containing silyl group UL94 V-0
Acrylic Adhesives Cemedine Co.,Ltd. Acrylic polymer containing silyl group

Test

After applying adhesive on the cross section (10mm x 10mm) of a bar, adhere it to another bar covering total surface of 50mm2 (5mm x 10mm), then pull the bars in the direction shown in picture.

Results

After pulling, the top bar broke. Adhered parts remained intact.
This shows that strength of adhesive is stronger than tensile strength of SunForce.
Adhesive strength > Tensile strength of SunForce
