and compatibility for a smooth coating system. Marine tie-coats add to the overall
performance and lifespan of the coating system by assuring a smooth, uniform surface
for following coats and fostering strong bonding between layers. You can rely on
URSA Associates to provide marine tie-coats of finest quality that satisfy the
exacting requirements of the maritime industry, guaranteeing the best possible
protection and longevity for marine buildings and boats.
Purpose
A tie-coat serves multiple crucial purposes in marine coatings:
- Adhesion:Its primary function is to enhance adhesion between
different layers of coatings, especially during transitions from one type of
coating to another.
- Barrier: Acting as a barrier coat, it prevents interactions
between incompatible coatings, thus averting delamination or diminished
performance.
- Surface Preparation:Applied over prepared surfaces, tie-coats
ensure optimal conditions for subsequent coating applications.
Key Characteristics
Tie-coats possess specific characteristics essential for their effectiveness:
- Compatibility: They are meticulously formulated to be
compatible with both the coatings applied over and under them, ensuring chemical
harmony for proper adhesion.
- Adhesion Promoter: Containing ingredients like resins and
additives, tie-coats promote superior adhesion by forming strong bonds with both
the substrate and the subsequent coating.
- Smooth Finish: Often providing a smooth and uniform surface,
tie-coats create an ideal substrate for the application of subsequent coatings.
- Flexibility: Certain tie-coats are engineered to offer
flexibility, crucial in marine environments where structures may undergo
movement.
Applications:
Tie-coats find application in various scenarios:
- Between Coating Systems: They are used during transitions from
one coating system to another, such as from an epoxy primer to antifouling paint
or between different types of topcoats.
- Over Prepared Surfaces:Applied over properly prepared surfaces,
including cleaning, sanding, and priming, to ensure an optimized substrate.
Types of Tie-Coats:
Different types of tie-coats cater to specific needs:
- Epoxy Tie-Coats:Widely employed to enhance adhesion between
epoxy primers and subsequent coatings, renowned for their excellent adhesion
properties.
- Vinyl Tie-Coats:Suitable for transitioning between various
coatings, including those based on vinyl.
- Polyurethane Tie-Coats: Utilized in systems involving
polyurethane coatings to augment adhesion and compatibility.
Marine tie-coats play a crucial role in achieving a robust and long-lasting
protective coating system. Choosing the right type of tie-coat and following proper
application procedures are essential for achieving the desired adhesion and
performance in marine environments.
