Diamolac High Build Pre-catalysed Nitrocellulose Lacquer

320 Diamolac 1k HB Precat Clear Lacquer

320 Diamolac HB Precat Clear Lacquer is a high-quality, single-component, nitrocellulose-modified pre-catalysed lacquer designed for industrial applications on interior furniture and general woodwork. This lacquer delivers a high build with a silky smooth feel, making it ideal for industrial production lines.

Key Features:

• Product: Modified pre-catalysed nitrocellulose lacquer
• Gloss Levels: 10%, 30%, 50%, 100%
• Thinning: TZ075 Lacquer Thinners (can be thinned up to 10% by volume)
• Drying Time: Tack free in 20-30 minutes; recoat in 2-3 hours (oven curing at 40°C reduces recoat time to approximately 30 minutes, cooling required before recoating)
• Interior Exposure: Very good
• Yellowing Characteristics: Typical of nitrocellulose-based lacquer
• Water Resistance: Suitable only for splash resistance; for wet areas, use two-component chemically resistant coatings
• Exterior Exposure: Not suitable (must be protected from direct sunlight, rain, and water condensation)
• Container Sizes: 4L, 20L
• Sealer: May be used as a self-sealing system, recommended to use with 320 Diamoseal HB Sealer for open grain timber or suitable two-component polyurethane sealers
• Coverage:
  • Theoretical: 15-20 square meters per liter
  • Practical: 6-8 square meters per liter (spray application)

Uses: 320 Diamolac HB Precat Clear Lacquer is used as an industrial-grade, quick-drying NC pre-catalysed lacquer over suitably prepared timber surfaces. It is ideal for coating most internal furniture, exhibiting excellent film build, ease of use, short recoat times, and good durability.

Application Instructions:

Timber Preparation:

• Ensure timber has a moisture content not exceeding 12%.
• Prepare and sand timber with at least 180 grit sandpaper and wipe clean prior to application.
• Avoid applying coatings over oily timbers or knots containing sap; a suitable barrier coat may be necessary to avoid delamination or discoloration of topcoats.

System 1: Self-Sealing

Clear Finish:

1. Apply a self-sealing coat of 320 Diamolac HB Precat Clear Lacquer (10% or 30% gloss) and allow to cure for 2 hours at room temperature.
2. Sand with 320-400 grit paper and recoat with 320 Diamolac HB Precat Clear Lacquer at the desired gloss level.
3. If a third coat is needed, allow 2 hours cure and repeat step 2.

Stained Finish:

1. Apply the desired stain and allow for the recommended drying time.
2. Apply a self-sealing coat of 320 Diamolac HB Precat Clear Lacquer and allow to cure for 2 hours at room temperature.
3. Sand with 320-400 grit paper and recoat with 320 Diamolac HB Precat Clear Lacquer at the desired gloss level.
4. If a third coat is needed, allow 2 hours cure and repeat step 3.

System 2: Sealing

Clear Finish:

1. Apply 320 Diamoseal Precat HB Sealer and allow to cure for 1-2 hours at room temperature.
2. Sand with 320-400 grit paper and recoat with 320 Diamolac HB Precat Clear Lacquer at the desired gloss level.
3. If a third coat is needed, allow 2 hours cure and repeat step 2.

Stained Finish:

1. Apply the desired stain and allow for the recommended drying time.
2. Apply 320 Diamoseal Precat HB Sealer and allow to cure for 1-2 hours at room temperature, or 30 minutes at 40°C.
3. Sand with 320-400 grit paper and recoat with 320 Diamolac HB Precat Clear Lacquer at the desired gloss level.
4. If a further coat is needed, allow 2 hours cure at room temperature or 30 minutes at 40°C and repeat step 3.

Note: Heavier coats will require longer recoat times. Force curing of 320 Diamolac HB Precat Clear Lacquer at 40°C will allow a recoat time of approximately 30 minutes.

Precautions:

• Avoid applying excessively high film builds to prevent defects and cracking.
• Nitrocellulose lacquers will yellow over time.
• Clear lacquer film will not prevent timber discoloration from UV light exposure.
• Not recommended for use on vanity or kitchen bench-tops exposed to water pooling or high humidity; use two-component chemical resistant coatings in such conditions.
• Single component 320 Diamoseal Precat HB Sealer may be replaced with a suitable two-component polyurethane sealer for higher film builds and improved resistance properties. Follow recommended recoat times and sand between coats with 320-400 grit sandpaper.
