Product
HS-3401 HT80
SHAIC HS-3401HT 80 is designed for welded joint protection for high temperature up to 80°C(176°F) of plastic coated steel pipelines such as PVC, polypropylene, polyethylene, or fusion bonded epoxy. It has a thick irradiated cross-linked polyethylene backing coated with heat sensitive adhesive and two parts of liquid epoxy primer. Apply epoxy primer to the pipe surface and then adhesive flows and forms a reliable corrosion protection seal onto epoxy and adjacent coating surface. SHAIC HS- 3401HT 80 is complied with EN 12068-C HT 80 UV.

Long-term Corrosion Protection

After heating, formed corrosion protection seal and strong backing provides outstanding waterproofing effect and high chemical resistance. SHAIC HS-3401HT 80 3-layer corrosion protection system resists impact, abrasion and ultraviolet light as well as excellent resistance against cathodic disbondment, dielectric breakdown.

Bulk Rolls

SHAIC HS-3401HT 80 is supplied in bulk rolls, which is cut in the field for any size of pipe. No need to drive to warehouse and just cut customized length in the field in time that reduces inventories and saves the cost & time

Installation

HS-3401HT 80 is used for 3 layer coating system upon customers' specific project requirement.

Please contact with our representative for appropriate installation. Apply epoxy primer over foreign matter- free and preheated surface. Wrap the sleeve around the pipes. Fix the center of preheated patch closure on the overlapped end and start to heat sleeve in the center. Move the torch around pipe circumferentially to heat the left and the right of sleeve. Finish off by heating vertically over the entire sleeve to ensure a uniform adhesion and by using a roller or gloved hands to remove wrinkle and air.

Epoxy Primer

SHAIC EPOXY PRIMER is designed for 3 layer coating system for superior corrosion protec- tion of field joints of steel pipelines. Epoxy primer corrosion protection resists impact, abrasion as well as cathodic disbondment, di- electric breakdown.

Application Procedure

  1. 1. Prepare the pipe surface as recommended in the produst application.
  2. 2. Pour cure into base as 3 parts base to 1 part of cure. Stir the mixture for a minimum of 30 seconds to ensure homogeneous mixture.
  3. 3. Apply mixed epoxy primer as indicated in the product ap- plication.
  4. 4. Epoxy Primer covers 20 sq.m/gallon (215 sq./gallon) or 5.3 sq.m/liter (57 sq.m/liter).
    This coverage is based on 4 to 6 mils of thickness & as- suming 20% waste.
