HLD T400
Honglida
The Biadhesive Pipe wrapping tape T400 is manufactured in 30mil, 32mil, 40mil, 43mil
thickness. Standard color is Black.
The Biadhesive Pipe wrapping tape T400 ensures an easy and fast coating application. It is
“cold” applied under prevailing environment temperatures of the products and surface, no need
extra heat. Release Liner should be discarded during application.
The Biadhesive Pipe wrapping tape T400 produces a strong cohesive bond to the primed
steel surface, at the spiral overlap and to the mechanical outer layer. Its fully amalgamating
overlapping areas forms a sleeve-type coating.
The Biadhesive Pipe wrapping tape T400 ensures a long time performance of coating, thanks
to the high electrical and chemical resistance to both acids and alkalis attacks and thanks to its
properties of high strong resistance to the cathodic disbondment.
The Biadhesive Pipe wrapping tape T400 ensures a high economical advantage because
they match the highest productivity with very low investment and produce a minimum waste. It is
compatible with generic plant coating systems thus saving store cost.
High adhesion and shear resistance
Resistance to corrosion disbandment
High electrical resistance
High dielectric strength
High corrosion protection for steel substrates
