개요

록타이트 B-15 (Loctite Frekote B-15) is a one-part, solvent-based polymer mold sealer designed to restore and prepare composite and metal molds that suffer from micro-porosity, small scratches or surface imperfections.

Applied as a thin base coat, it:

  • Seals micro-porosity and fine defects in the mold surface

  • 제공합니다 clear, colorless film that does not change the tool appearance1

  • Offers high thermal stability for elevated-temperature molding processes

  • Ensures no contaminating transfer to molded parts when correctly applied

Used in combination with Loctite Frekote release agents, B-15 acts as an excellent base coat, enhancing both release performance 그리고 mold life.

주요 특징 및 장점

  • 1-part, solvent-based polymer sealer
    Ready-to-use liquid; no mixing required. Cures at 실온, simplifying mold preparation.

  • Seals porosity, scratches and imperfections
    Penetrates and seals micro-porosity, small surface scratches and minor defects, restoring a smooth, sealable surface on composite and metal tools.

  • High thermal stability
    다음 대상에 적합 elevated molding temperatures, maintaining film integrity over multiple cycles.

  • No contaminating transfer
    Properly cured B-15 leaves no contaminating transfer to molded parts, helping maintain surface quality and downstream bonding/painting.

  • Ideal base coat for Frekote release systems
    Used before Frekote release agents to improve release performance, reduce sticking and extend mold life.

  • Clear, colorless finish
    Maintains good visibility of the mold surface and repairs; useful for inspection and high-quality composite work.

일반적인 적용 사례

Loctite B-15 is used as a mold sealer / mold preparation coating for:

  • Composite molds

    • Carbon fiber, fiberglass and other advanced composite tools

    • Tools used in RTM, vacuum bagging, hand lay-up and autoclave processes

  • Metal molds

    • Aluminum and steel molds with micro-porosity or light scratching

    • Rotational molding and other processes where mold porosity affects release

  • Aerospace, automotive and industrial components

    • Composite panels, fairings, covers and structural parts

    • High-value tools where extended mold life and consistent release are critical

How to Use Loctite B-15

Always follow the current Henkel TDS/SDS and your internal process specification. Steps below are a general overview.

1단계 - 곰팡이 청소

  1. 철저하게 곰팡이 청소 to remove waxes, old release agents, oils, resins and contaminants.

  2. 권장되는 몰드 클리너 / 솔벤트 보푸라기가 없는 천을 사용하세요.

  3. 표면이 다음과 같은지 확인합니다. dry and at the recommended temperature before sealing.

2단계 – 신청

  1. Apply Loctite B-15 with a clean cloth, pad or spray, depending on your procedure.

  2. 근무 small sections, wiping a thin, even film over the surface.

  3. Avoid heavy puddles; the goal is to wet and seal the surface, not build a thick coating.

3단계 - 여러 번 코팅하기

  1. 일반적으로, multiple light coats are applied to fully seal porous areas (refer to TDS for number and timing).

  2. 각 코트는 dry / flash off at room temperature before applying the next.

4단계 – 경화

  1. After the final coat, allow B-15 to cure fully at ambient temperature for the time specified (often up to 24 hours).

  2. Once cured, the mold is ready for application of the chosen Frekote release agent or for the next stage in your process.

Step 5 – Release agent application

  • 적용 Frekote release coating on top of B-15 according to its own instructions.

  • Together they create a sealed, low-adhesion surface that supports multiple molding cycles.

안전 및 취급

  • Loctite B-15 is solvent-based and typically flammable – keep away from heat, sparks and open flames.

  • 에서만 사용 환기가 잘 되는 장소; 증기를 흡입하지 마세요.

  • 피하다 피부와 눈 접촉; 적절한 착용 개인 보호 장비 (gloves, goggles, protective clothing).

  • Do not allow product to enter 배수로 또는 자연 수로.

  • 보관하십시오. 원래의, 단단히 닫힌 용기 점화원에서 떨어진 서늘하고 건조한 곳에 보관하세요.

자주 묻는 질문

Q1: What is Loctite B-15 mainly used for?
Loctite B-15 is mainly used as a mold sealer ~을 위해 composite and metal tools with micro-porosity, fine scratches or surface imperfections, providing a sealed base for release agents.

Q2: Is Loctite B-15 a release agent by itself?
No. It is primarily a sealer, not the final release layer. It is usually used first, followed by a Frekote release agent to achieve optimum part release and multi-cycle performance.

Q3: On which substrates can I use B-15?
B-15 is formulated for composite molds (e.g. carbon, glass fiber tools) 그리고 metal molds such as aluminum and steel. Always test on any unusual substrate before full-scale use.

Q4: Will B-15 change the appearance of my mold surface?
No significant change is expected. It forms a clear, colorless film, maintaining visibility of the mold surface for inspection and finishing.

Q5: Does Loctite B-15 transfer onto molded parts?
When correctly applied and fully cured, B-15 provides no contaminating transfer to the molded parts, helping protect surface quality and downstream painting or bonding.

Q6: What temperature range can it withstand?
B-15 is designed with high thermal stability for typical composite molding temperatures; always check the current TDS for specific temperature limits in your process.

Q7: How often do I need to reapply B-15?
You generally reapply B-15 when the mold surface shows wear, porosity exposure or after refurbishment. Routine cycles are usually handled by the release agent alone; B-15 is used when re-sealing 필요합니다.
