This modified silicone sealant hardens chemically, reacting between its base material and hardening agent, and features a low-modulus, low tensile stress design. It cures into a form with outstanding weather resistance, durability, and dynamic followability, striking an ideal balance in sealant performance. Additionally, its excellent stain resistance and strong adhesion to paint ensure prolonged aesthetic preservation of buildings.

Sealing Material Properties

The combined ratio refers to the ratio of masses. A “1” in test results signifies non-compliance, while “NF” denotes no damage. The Type 1 tensile adhesion test follows JIS A1439 standards. “After heating” denotes the pressure heating temperature in the durability test, set at 80℃ for products not classified for durability. These results are indicative values.

Sealing Material Properties

A test result of “1” indicates that the product is not tested, and “NF” indicates that there is no damage.
The H-type tensile adhesion test is conducted in accordance with JIS A1439. The heating temperature “after heating” is the compression heating temperature of the durability test, and is 80℃ for products without durability classification. The results are representative values.

List of Suitable Materials for Appropriate Use

※Notes:

●When installing the primer, be careful not to protrude or fly. Once completely cured, the primer will firmly adhere to the substrate and will not dissolve in organic solvents.
Please wipe it clean with a cloth soaked in toluene etc. as soon as possible on the day of construction. Please be aware that if you scrape or otherwise remove the adhesive after it has hardened, you may damage the underlying surface during removal.

Construction Procedure

1 Meeting before construction

Thoroughly consider the fit of the joints (shape and dimensions, secondary drainage treatment, construction conditions, etc.).

2 Preparation before construction

Please select materials, primers, auxiliary materials, and prepare construction instructions.

3.Inspection before construction

Please check the construction location, joint shape, dimensions and level differences.
Check for defects on the adherend (jumpers, chips, cracks, etc.) and repair as necessary.

4 Cleaning and drying the base

Check whether the adherend is sufficiently dry.
To prevent adhesion failure due to oil, dirt, dust, etc., carefully clean the surface to be adhered by wiping it dry and then wiping it with a clean cloth soaked in solvent.
Choose a cleaning solvent that can sufficiently remove oil, dirt, and other factors that inhibit adhesion from the adherend (such as methylcyclohexane). Please use n-hexane to dissolve the painted surface.

5 Loading backup material

Load backup material appropriate for the joint dimensions.
If there is not enough room for the depth of the joint, attach a bond breaker to the bottom to ensure two-sided adhesion. (For working joints)

6 Paste masking tape

Please be careful not to let the tape dig into the surface to which it is attached.
No adhesive remains, and the solvent used in the primer does not have a negative effect on adhesion. Use masking tape.

7 Primer application

Apply evenly with a brush to avoid uneven application.
Be careful when applying the primer so that it does not scatter or protrude.
Please ensure the specified drying time and fill the sealant within the effective time after application.

8 Filling with sealant

Consider the nozzle angle and filling speed so that sufficient pressure can be applied to the adherend using a nozzle that matches the width of the joint, and that it can fill to the bottom of the joint. 3 Inspection before construction

9 Spatula finish

After filling the sealant, finish it immediately with a spatula.
When finishing with a spatula, apply sufficient pressure to create a smooth finish.

10 Masking tape removal

The masking tape adhesive may transfer to the adherend, so please remove the masking tape immediately after filling.

11. Cleaning around the joints

12. Curing of sealant

13. Comprehensive inspection

*During construction, performance cannot be achieved unless materials are used appropriately. Please follow the construction procedures, etc. when handling.

Handling Precautions

This describes product performance under appropriate conditions and assuming proper storage, handling, and use. It merely describes general construction methods and procedures. The selection, storage, treatment and use of products, construction methods and procedures, etc. under the relevant construction conditions in individual and specific construction work are the responsibility of the construction contractor, who is an expert user.

Handling work

1 Wear protective gloves and an apron while handling.
2 When working in a closed room, ensure adequate ventilation.
3. Wear safety glasses, protective masks, etc. depending on the work situation.
4. Wash your hands and gargle thoroughly after handling.
5 Avoid direct skin contact.
6 Avoid contact with eyes.
7 Do not breathe vapor.
8 Do not swallow.
9 Please strictly refrain from smoking while using Hamatite.
10 Please cure without touching until hardened.
11 Please entrust waste disposal to an industrial waste disposal company.

First Aid

1 If it gets on your skin, immediately wipe it off with a rag and wash thoroughly with plenty of water and soap.
2 If itching or inflammation develops, consult a doctor immediately.
3 In case of contact with eyes, rinse thoroughly with clean water and consult an ophthalmologist immediately.
4 If you feel unwell after inhaling the vapor, immediately move to a place with fresh air.
5 If you experience any abnormalities such as a headache, please consult a doctor immediately.
6 If swallowed, drink plenty of water or milk, induce vomiting, and seek medical advice immediately.

Handling location

1 Never use the product near fire.
2. Install a local exhaust system in the handling area.
3 Keep out of reach of children.
