Our Innovation Journey

Zhejiang Sanfreund Technology Co., Ltd. traces its origins to Japan, where its division,
Hokkaido WAKA Co., Ltd., laid the groundwork for advanced anti-corrosion coating
solutions. With over 20 years of experience in tank lining repair and the development of
specialized FRP (Fiber-Reinforced Polymer) coating, the company pioneered the
application of lining coatings for petrochemical storage tanks, leading to global
advancements in corrosion and leakage prevention.

In September 2019, Hokkaido WAKA’s experts partnered with the Sinopec Qingdao
Safety Engineering Institute to test new membrane materials. Through immersion
experiments and tests across 14 different chemical media, the membrane’s performance
and durability were rigorously validated, proving its reliability in varied conditions and
solidifying its reputation in corrosion protection.
