SynthoGlass PPR-220 two-part epoxy Primer (aka SUBLV)

Product Name

SynthoGlass PPR-220 two-part epoxy Primer (aka SUBLV)

Brief Description

The SynthoGlass PPR-220 is a solvent-free, chemically resistant, two-part bulk epoxy primer. It is specifically designed to optimize the bond strength between pipe surfaces (or epoxy fillers) and composite repair wraps or tapes, such as those in the SynthoGlass system. This primer also serves as a critical component for corrosion prevention and offers high-build capability without slumping or sagging.

Popular Applications & Uses

- Optimizing bond strength for composite pipe repair wraps and tapes.- Providing a corrosion prevention barrier for pipes.- Used atop filler compounds and underneath repair wraps or tapes.- Facilitating the transition of aggressive changes in geometry or large defects prior to installing composite repair systems.- Repair and reinforcement of various pipe materials, including copper, steel, stainless steel, PVC, FRP, clay, concrete, and rubber, when used with SynthoGlass wraps.- Acting as a bonding agent and promoter between the pipe and composite.- Ensuring load transfer between the pipe and composite.- Offering first contact protection against internal chemicals that may come into contact with the repair system.

Industries that Commonly Use It

- Petroleum Industry, Products or Services- Energy- Construction/Building Services- Marine- Chemical Industry- General Manufacturing- Government & Military- Industrial Supply- Engineering Services

Special and Unique Features

- Solvent-free formulation.- Highly chemically resistant to a wide variety of inorganic acids, alkalis, salts, and organic media.- Two-part bulk epoxy system for robust performance.- High-build capability without slumping or sagging, allowing for significant thickness in a single application.- Can be over-coated as soon as it is dry to the touch, speeding up repair processes.- Machinable once fully cured, allowing for precise finishing.- Available in convenient BiPack pouches (4 oz and 16 oz options) for mess-free mixing and application.- Compliant with key industry standards such as US DOT CFR 192 and 195, CSA Z662, ASME PCC-2 Article 401, and ISO 24817.

Surface Compatibility

- Any metal surface.- Surfaces with epoxy fillers added.- Compatible with various pipe materials including copper, steel, stainless steel, PVC, FRP, clay, concrete, and rubber, when used as part of the SynthoGlass repair system.

Known backups / known substitutes

- Other primers from CSNRI Composites, such as PPR-290, PPR-460, PPR-580, and PPR-590, are designed for different temperature ranges and chemical compatibilities within their engineered composite repair systems.- Fillers like EPN-101, EPN-242, and ESN-202 are often used in conjunction with PPR-220 as part of a complete repair system.

Comparison Note

SynthoGlass PPR-220 stands out as a high-performance, solvent-free epoxy primer specifically engineered to enhance the efficacy and durability of composite pipe repair systems like SynthoGlass. Its robust chemical resistance, high-build characteristics, and machinability make it a crucial component for achieving optimal adhesion and long-lasting corrosion protection in challenging industrial environments. Unlike general-purpose primers, PPR-220 is formulated to work synergistically with specific composite repair wraps, ensuring a comprehensive and reliable solution for pipe integrity.
